Great addition to my daily vitamins

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha BRAIN for a few weeks now, and I can genuinely say it’s made a noticeable difference in my mental clarity and focus. Whether I’m working, studying, or just trying to stay sharp, it helps me stay dialed in without any jitters or crash. I love that it’s made with natural ingredients and designed to support memory and cognitive function. This supplement has become a go-to part of my daily routine, and I definitely recommend it for anyone looking to boost brain performance naturally!

Works ok

[This review was collected as part of a promotion.] This product was ok, i didn't notice a huge change in my clarity, but seems like I had a little more energy. My tummy seemed to handle it ok. I think it's a little spendy but if it works for you then it fits it's worth it. I do think it's strange that it comes in a 2 week supply.

AMAZING SUPPORT TEAM AND PRODUCT!

First and foremost, I need to thank Aaron especially and the onnit team for dealing with a shipping issue with the utmost professionalism and speediness. The support team is just as good as the products, and that is no small feat. I cannot recommend this product enough! It’s effects (whether actual or placebo) are significant, and that’s all that matters to me.

Good Focus

[This review was collected as part of a promotion.] I received this product free from ONNIT and Influensters for my honest review. Alpha Brain has been something I have enjoyed trying. It helps with focus throughout the day and I felt more alert. It did not make me feel weird like some supplements do, but it is a mild feeling of just being alert. They are easy to take and use and do not have to be taken daily or anything. I would recommend them just to have a little extra focus when needed.

part of my daily routine.

[This review was collected as part of a promotion.] Alpha Brain has become part of my daily routine.” I started taking Onnit’s Alpha Brain to help with mental clarity and focus during long workdays—and I can genuinely feel the difference. Within about a week, I noticed I was less scatterbrained and more in the zone, especially during meetings or deep work sessions. It’s not like a jolt of energy or a caffeine buzz—more like a subtle sharpening of your thoughts. I appreciate that it’s stimulant-free too, so there’s no crash. Definitely worth trying if you’re looking for a natural cognitive boost.

Great, feeling energized and motivated

[This review was collected as part of a promotion.] I have been waiting to review these so I can actually try them for longer than just a day, these are amazing. I feel like I wake up with more energy every day and works amazingly. I feel more focused and motivated, especially as a stay at home mom, I had the energy to do chores and go to the gym and go to the park with my little one. This has great packaging too, its not a huge bottle like other vitamins. I would buy again

Improves memory and focus!

[This review was collected as part of a promotion.] I received this product complimentary from Influenster and Onnit in exchange for my honest review. I have been struggling with my memory lately, and after taking these for a week I have already noticed improvements! My focus is also on point, giving me an extra edge at work. The capsules are made well and easy to swallow. I haven’t experienced any jitters or other side effects. This product has great ingredients that truly work to improve mental clarity! I would recommend these supplements for anyone looking to improve their cognitive function.

Bad reaction

Unfortunately, this product is not for everyone. I love Onnit and their mission! However, I reacted to this product with nausea and vomiting---- followed by about 12 hours of G.I. issues. It made my head feel like Ila balloon was getting blown up inside of it. It had the opposite effect it was supposed to and I unfortunately cannot keep taking it. Otherwise, I love this company and their products.
